I used to use the Red Sea MINI, which had a good effect, but it didn't have intelligent speed regulation. It kept more than 2000 revolutions for a long time. There was no noise, but it always seemed that something was missing. The black ice 400 seemed too big. For safety reasons, I chose a smaller one. The current fan is about 800 revolutions, which is very quiet. The standby is about 23 degrees. The game has not yet been tested,
Most dissatisfied
Fins are slightly prickly
summary
Low sound, good heat dissipation, large fan, good cooling effect
